Question

After upgrading to Firefox 3.6, when I try to launch SCORM courses, I get an alert that tells me "Error Creating Debug Logs:  undefined".(see attached error)  After hitting 'OK", the course never launches.  I tried my course in Test Track, and it works fine.

Answer

The first thing you need to look at is the version of the SCORM Engine.  Chances are, you are running SCORM Engine version 2007 or earlier.  Something in that latest version of FireFox does not like what we were doing in the log.js file back in the day.  The reason it works in Test Track is because Test Track is running the latest and greatest version of the SCORM Engine, we handle the creation of debug logs a little differently now.

There are a couple of ways to fix the issue.  

1.  Upgrade to the latest version of SCORM Engine.  Why should you upgrade?

2.  If upgrading is out of the question, you can replace your log.js file with the attached file.  It should get you around the issue.

Please note that when you make changes like option 2, rename your old log file before just overwriting it.
